Application Service Provider)A third-party entity that manages and distributes software-based services and solutions to customers across a wide area network from a central data center.
A popular file sharing service developed by Bram Cohen that prevents people from downloading constantly unless they are willing to share in the overall transmission load on the network.
Can read CD-ROMs and can write onto CD-R disks; With CD-RW drives and disks, you can treat the optical disk just like a floppy or hard disk, writing data onto it multiple times.
In a PC, the name assigned to the first serial port; PCs are typically designed to support up to four serial ports; The term originated before the days of the mouse, when the serial port was primarily used for modem COM-munications.
Short for Concurrent Versions System, an open-source, network-transparent program that allows developers to keep track of different development versions of source code.
(File Allocation Table) The original file system used in DOS, Windows and OS/2. The FAT keeps track of where data are stored on disk. When the disk is high-level formatted, the FAT is recorded twice and contains a table with an entry for each disk cluster.
A programming environment integrated into a software application that provides a GUI builder, a text or code editor, a compiler and/or interpreter and a debugger. Integrated Development Environment.
(NT File System) An optional file system for Windows NT, 2000 and XP operating systems. More advanced than FAT32. It improves performance and is required in order to implement numerous security and administrative features in OS.
(Operating System) Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.
Read Only Memory; Computer memory on which data has been prerecorded; Once data has been written on a ROM chip, it cannot be removed and can only be read.
Pertaining to a number system that has just two unique digits; 0 and 1; All operations that are possible in the decimal system are equally possible in the binary system; For a computer the binary system is more natural because of its electrical nature (charged versus uncharged).
A value associated with an element, consisting of a name, and an associated (textual) value. Also: An attribute is a parameter to an element declared in the DTD. An attribute's type and value range, including a possible default value, are defined in the DTD.
A style sheet format for HTML documents endorsed by the World Wide Web Consortium. CSS1 (Version 1.0) provides hundreds of layout settings that can be applied to all the subsequent HTML pages that are downloaded. CSS2 (Version 2.0) adds support for XML, oral presentations for the visually impaired, downloadable fonts and other enhancements.
A deprecated element or attribute is one that has been outdated by newer constructs. Deprecated elements may become obsolete in future versions of HTML. The index of HTML elements and attributes in the Techniques Document indicates which elements and attributes are deprecated in HTML 4.0. Authors should avoid using deprecated elements and attributes. User agents should continue to support for reasons of backward compatibility.
Short for document type definition. A DTD states what tags and attributes are used to describe content in an SGML, XML or HTML document, where each tag is allowed, and which tags can appear within other tags. For example, in a DTD one could say that LIST tags can contain ITEM tags, but ITEM tags cannot contain LIST tags. In some editors, when authors are inputting information, they can place tags only where the DTD allows. This ensures that all the documentation is formatted the same way. Applications will use a document's DTD to properly read and display a document's contents. Changes in the format of the document can be easily made by modifying the DTD.
This document uses the term "element" both in the strict SGML sense (an element is a syntactic construct) and more generally to mean a type of content (such as video or sound) or a logical construct (such as a header or list). The second sense emphasizes that a guideline inspired by HTML could easily apply to another markup language. Note that some (SGML) elements have content that is rendered (e.g., the P, LI, or TABLE elements in HTML), some are replaced by external content (e.g., IMG), and some affect processing (e.g., STYLE and SCRIPT cause information to be processed by a style sheet or script engine). An element that causes text characters to be part of the document is called a text element.
The HTML tag that divides a Web page into sections (frames). The following HTML divides the screen page into two horizontal frames with the top frame having 25% of the screen and the bottom frame having 75%.
Strict is a trimmed down version of HTML 4.01 that emphasizes structure over presentation. Deprecated elements and attributes (including most presentational attributes), frames, and link targets are not allowed in HTML 4 Strict. By writing to HTML 4 Strict, authors can achieve accessible, structurally rich documents that easily adapt to style sheets and different browsing situations. However, HTML 4 Strict documents may look bland on very old browsers that lack support for style sheets.
The Transitional DTD includes presentation attributes and elements that W3C expects to move to a style sheet. Use this when you need to use HTML's presentational features because your readers don't have browsers that support Cascading Style Sheets (CSS)
Validation is a process whereby documents are verified against the associated DTD, ensuring that the structure, use of elements, and use of attributes are consistent with the definitions in the DTD.
(World Wide Web Consortium, www.w3.org) An international industry consortium founded in 1994 by Tim Berners-Lee to develop standards for the Web. It is hosted in the U.S. by the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT (www.csail.mit.edu/index.php). More than 400 organizations worldwide are involved, and members work on projects called "Activities." The W3C has standardized many of the fundamental technologies of the Web, including HTML and XML, URLs and URIs, the SOAP protocol and the P3P privacy description.
A type of data transmission in which a single medium (wire) can carry several channels at once. Cable TV, for example, uses broadband transmission. In contrast, baseband transmission allows only one signal at a time.
A network architecture in which each computer or process on the network is either a client or a server. Servers are powerful computers or processes dedicated to managing disk drives, printers, or network traffic. Clients are PCs or workstations on which users run applications. Clients rely on servers for resources, such as files, devices, and even processing power.
(HyperText Transfer Protocol) Defines how messages are formatted and transmitted, and what actions web servers and browsers should take in response to various commands.
A common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN, contains multiple ports, When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
Allows anyone to edit, delete or modify content that has been placed on the Web site using a browser interface, including the work of previous authors.
Commonly referred to as WiMAX or less commonly as WirelessMAN or the Air Interface Standard, IEEE 802.16 is a specification for fixed broadband wireless metropolitan access networks (MANs)
The condition wherein the data transferred to a buffer exceeds the storage capacity of the buffer and some of the data overflows into another buffer which the data was not supposed to go into. The overflow can corrupt data that is already contained in the other buffer.
A system of digital certificates, certificate authorities, and other registration authorities that verify and authenticate the validity of each party involved in an internet transaction.
